It's an encouraging sign for Dumervil, who returned to practice on a limited basis Friday.

Dumervil is officially listed as questionable as well as rookie safety Brynden Trawick (ankle). Starting cornerback Lardarius Webb (abdominal) is probable, meaning the team is as healthy as it’s been throughout the season.

“Yes, I would say so,” Ravens coach John Harbaugh said. “If you look at the course of the season and even last year, this is probably as healthy as we’ve been.”

"Obviously, we’d like to get sacks," defensive coordinator Dean Pees said. "I think you’d be surprised, though, how many times we actually hit the quarterback. When you watch the film, we may not be getting a sack if the ball is coming out quick, and there’s no way a guy can do that. We’re getting quite a few hits.

"Elvis has been out, and that’s been a little bit of a factor, but the truth is the ball is coming out a lot quicker in these last two games. That’s smart football by their part.”

Pees said teams have been using a lot of maximum-protection blocking schemes against the Ravens during the past two games.

“If you notice, whenever they put two or three people back in the backfield, you’re getting seven-man protection," Pees said. "So on a four-man rush, you’ve got seven blocking four. I think we’ve made people close it in a little bit.

"If you try to protect a little more, maybe not get as many guys out but do a little protection. At the same time, we need to do a better job. There are a couple of things we could have done in that game. We had some opportunities, and we just didn’t quite get there. We need to improve on that.”

For the Lions, cornerbacks Chris Houston (toe) and Darius Slay (knee) are doubtful.
